Overview
Diethylenetriamine (CAS 111-40-0 ), commonly abbreviated as DETA, is a polyamine building block used across adhesive, coating, and polymer manufacturing. Its multiple reactive amine groups make it a functional intermediate for curing agents and chemical synthesis.
Buyers source it primarily as a reactive component rather than a finished additive. In epoxy systems, DETA acts as a room-temperature curing agent for coatings, flooring compounds, and structural adhesives.
Controlled crosslink density determines final film hardness and chemical resistance in these applications. Textile and paper processors use it to produce wet-strength resins and softening agents that improve substrate durability.
In polymer synthesis, DETA serves as a monomer for polyamide resins and imidazoline derivatives used in corrosion inhibitors and fuel additives. These derivatives are essential for industrial maintenance and protection.
Personal care formulators incorporate DETA-derived intermediates into conditioning agents and chelating systems for rinse-off and leave-on products. This versatility makes it a staple in specialty chemical portfolios.
Diethylenetriamine is supplied as a clear to pale yellow liquid in drum, IBC, and bulk tanker quantities. Technical grade is the standard commercial form, with purity specifications typically at 99% minimum.
Buyers requiring tighter amine content or color specifications can source material against defined CoA parameters. Quality is maintained according to industry standards to ensure consistent performance in reactive processes.
